Replacement circuit for SFPR1 and SFPR4 series
This electronic circuit board controls Sentera SFPR series transformer fan speed controllers. Via an external contact, it is possible to switch between two optimal motor speeds (high/low operation). SFPR series are transformer fan speed controllers with an output that controls a gas valve. An air flow sensor or pressure relay is required to detect air flow (extraction fan). In case air flow is not detected within 60 seconds after the motor is started, the gas valve output is deactivated. Local safety regulations often dictate that gas can only be supplied after the kitchen hood exhaust fan above the stove has been activated. This makes the SFPR series the ideal fan speed controller for industrial kitchen hoods! Their TK monitoring function protects the motor against overheating.
